So with my routine playing slots at Bc game, I didn't feel that my Vip account had reached vip 8 or would soon reach Vip 9. Slowly but surely I will pursue a high vip to be able to get lots of bonuses.

I envy you for your imagination. Even at high levels the bonuses are not good, trust me. I am VIP 59 now and monthly for example is 0.02% of your wager. Meaning when you wager 10000$ you will get 2$ monthly bonus, of which you can claim half of it instantly and the rest goes to the "bank" and you can claim it in micro transactions over the next days. If you don't claim it in time (24 hours) it's basically forfeited. Weekly is like 0.06% of the wager, also tiny and the bank situation is the same.
So don't expect much because there isn't a lot to look forward to, straight up facts.
